\(\left(\frac{7}{5}-x\right)^3+\frac{3}{2}=0,5\)
\(\left(\frac{7}{5}-x\right)^3=\frac{1}{2}-\frac{3}{2}\)
\(\left(\frac{7}{5}-x\right)^3=-1=\left(-1\right)^3\)
\(\frac{7}{5}-x=-1\)
\(x=-1-\frac{7}{5}\)
\(x=-\frac{12}{5}\)
Vậy x = -12/5
=))
\(\left(\frac{7}{5}-x\right)^3+\frac{3}{2}=0,5\)
\(\left(\frac{7}{5}-x\right)^3=0,5-\frac{3}{2}\)
\(\left(\frac{7}{5}-x\right)^3=-1=\left(-1\right)^3\)
\(\Rightarrow\frac{7}{5}-x=-1\)
\(\Rightarrow x=\frac{8}{5}\)
Trả lời :
X = \(\frac{8}{5}\)

\(\left(\frac{7}{5}-x\right)^3+\frac{3}{2}=0,5\)
\(\Leftrightarrow\left(\frac{7}{5}-x\right)^3=0,5-\frac{3}{2}\)
\(\Leftrightarrow\left(\frac{7}{5}-x\right)^3=-1\)
\(\Leftrightarrow\frac{7}{5}-x=-1\)
\(\Leftrightarrow x=\frac{7}{5}-\left(-1\right)\)
\(\Leftrightarrow x=\frac{12}{5}\)
